An extension to load Ghidra scripts written in Scala

Introduction

Love ghidra but hate Java? If so, then this extension is for you! Just load this extension, and Ghidra will see and be able to load any scripts written in Scala. Just make sure their filename ends in .scala and drop them into any ghidra_scripts directory.

Now with 100% less Java! This version is written natively in Scala. Thanks to Edward J. Schwartz for the original Java implementation! This version also uses Gradle to automatically download and package the Scala compiler with the plugin.

Compilation

If you want to build the extension yourself, make sure you have gradle installed, and then run GHIDRA_INSTALL_DIR=/path/to/ghidra gradle buildExtension. If all goes well, you should get a message like:

8:58:01 AM: Executing task 'buildExtension'...

In this case, the file dist/ghidra_9.1.2_PUBLIC_20200221_ghidra-scala-loader.zip is the newly built extension.

Installation

Start Ghidra, and in the initial window (i.e., not the Code Browser), open the File menu, and select Install Extensions. Click the small plus icon in the top right of the window, and select the extension zip file that you built above. This should add an extension into the list, ScalaScriptProvider. Make sure the checkbox is ticked, and click OK to close the window. Ghidra will tell you that you need to restart to load the extension. Do so.

To make sure the extension loaded correctly, open the Code Browser, and under the Window menu, select Script Manager. If all is well, you should see a HelloWorld.scala script. Right click it, and select Run. You should see the hello world message print out to the Console.
